To all whom it may concern:

Be it known that I, FREDERICK R. HAW- nnr, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Bark-Rossing Machine, of which the following is a specification.

My invention has for its object the production of a particularly simple and efficient machine for rossing bark, and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing, in which like characters designate corresponding parts in all the views.

Figure 1 is a side elevation, partly in section, of one embodiment of my bark rossing machine. Fig. 2 is a front elevation thereof, parts being omitted. Fig. 3 is a sectional view illustrative of the manner of mounting the sheaves on their supporting shaft. Fig. 4: is a sectional view of the lower pressure .means of this bark rossing machine, and

contiguous parts. Fig. 5 is a sectional view of the abrading member and deflector, and contiguous parts. Fig. 6 is a section on line AA, Fig. 5.

My bark rossing machine comprises, generally, belt members provided with lengthwise sections and having portions opposed to each other, the space between said opposed portions forming a passage for the branches, the bark of which is to be rossed, means for actuating the belt members, and means for stripping the loosened bark from the branches.

1, 1 are angle iron side elements of the frame of this machine, and 2, 2 are legs for said elements.

3, t are belt members having portions 0pposed to each other and forming the passage for the branches, the bark of which isto be rcssed, these belt members being here shown as running over sets of sheaves 5, 56, 6 suitably supported by the frame, one set 5, 5 being arranged above the horizontal frame elements 1 and the other set 6, 6 below said elements. The lower sheaves 6, 6 are spaced apart a greater distance than the upper sheaves 5, 5, so that the lower belt member projects beyond the upper. As seen in Fig. 3, the sheaves 5 or 6 at each end of the belt members 3 or 4, are preferably arranged in a group of several units, but obviously, drums having grooved peripheries may be used instead of the sheaves 5, 56, 6. The belt members 3, 4 are of substantial width and feed the branches endwise with their axes substantially parallel to the direction of the feeding movement, and said belt members are provided with separated lengthwise sections the sections of the opposing portions of the belt members being arranged to engage the branches at three points. Preferably the belt members consist of ropes running over the sheaves 5, 5 and 6, 6, the sheaves being grooved for receiving the sections or ropes. Although preferably a continuous rope passing several times around the sheaves is employed for each belt member, obviously a plurality of such ropes may be employed, or a single continuous rope may be employed passing first around the sheaves 5, 5 and then around the sheaves ('3, 6. Suitable spring pressed tighteners 7, 8 coact with the belt members 8, l. The sheaves 5 and 6 are so-arranged relatively to each other that portions of the belt members 3, 4 extending between the sheaves are opposed to each other and form a passage for the branches, the bark of which is to be rossed, and also the sheaves are so arranged that the grooves of the sheaves 5 are arranged staggered with those of the sheaves 6 and thus the portions of the ropes on one side of the passage for the branches are arranged opposite to the interstices between the ropes of the belt member on the opposite side of said passage, so that the branches are engaged simultaneously by three of the rope sections.

Suitable pressure means cooperate with the portions of the rope confining the passage, and as here shown, these pressure means comprise a plurality of pairs of roll ing parts, the units of each pair being arranged above and below the portions of the belt members confining the passage for the branches and on opposite sides of a plane cutting said portions at a right angle, or in other words, out of vertical alinement.

Each of the upper rolling parts 9 extends full width of the belt members and is usually mounted on an axle 10 journaled in fixed bearings 11 on the frame element 1. Each of the lower rolling parts 12 comprises a plurality of grooved sheaves, Fig. 4, one sheave for each rope, and each sheave is carried by one arm of an angle lever 13 mounted on the shaft 14: which is common to all the levers 13, and a spring 15 is connected to the other arm thereof. Usually, a plurality of such pressure means is employed, and in order that the opposed portions of the belt members confining the passage for the branches may have an undulating motion for the purpose of facilitating the rossing of the bark on the branches passing through said passage, the upper and lower rolling parts 9, 12 are so adjusted that the distance between parallel planes tangent to the points ofengagement. of said opposed portions and said rolling parts 9, 10 of each pair is less than the combined thickness of said opposed portions.

For the purpose of adjusting one belt member relatively to the other, the axles 16 of the upper sheaves 5, 5 are journaled in boxes 17 adjustable along vertical guides 18 by means of vertical screws 19 supporting the boxes. The guides 18 supporting one of the axles 16 for one group of the upper sheaves, as the front group, are adjustable lengthwise of the elements 1, by means of screws 20 journaled in the frame and extending through threaded eyes 21 provided on the guides. One group of the lower sheaves 6 is also adjustable toward and from the other group to take up the slack due to stretching of the rope, by means of screws 22 suitably supported in a bracket 23 depending from the frame element 1 and extending through a threaded collar 24 provided on the bearings for the axles 25 of said sheaves 6.

The means for removing the loosened bark from the branches after said branches have passed between the belt members consists of strippers 26 located at the exit end of the passage for such branches, such strippers 26 being composed of suitable yielding material of sufiicient strength to strip the bark without scratching the naked branches.

Means is provided for drawing the branches out from between the belt members 3, 4 at a greater speed than they are carried by said belt members and thereby drawing them between the strippers at accelerated speed, and such means as here shown, comprises belt members 27, 28 simir lar in arrangement to the belt members 3, 4 and running over sheaves 29, 30 similar to the sheaves 5, 5-6, 6.

As before stated, the lower belt member 4 extends beyond the ends of the upper belt member 3 and such extension at the front of the machine forms a carrier on which the branches are placed and carried between the belt members 3, 4; and above such projecting portion of the lower belt member is provided means for guiding the branches between the belt members. Such guiding means consists of a deflector 32 extending crosswise of such projecting portion and spaced apart above the same, and a roller 33 in front of the deflector. Means is also provided for breaking the bark prior to the entrance of the branches between the belt members 3, 4, such means being here shown as an abrading member 34 extending crosswise of the projecting portion of the lower belt member between the deflector 32 and the roller 33, such member having forwardly and downwardly extending fingers 35 which terminate between the sections or ropes of the lower belt member and prevent the branches from entering the interstices between the ropes of the projecting portion and guide them over the abrading member. As the branches are fed onto such projecting portion of the lower belt member 4 the advance ends thereof engage the fingers 35 and thus the branches are carried over the abrading member and their advance ends engage the deflector 32 and are directed between the belt members 3, 4, the branches being pressed on the abrading member by the roller 33. While they are being carried over said abrading member, the bark thereon is bruised and scraped but not sufliciently to remove it from the branches.

The sheaves 5, 66, 6 and 26 and 27 are actuated in any suitable manner and are hereshown as connected to a main shaft 35 by power-transmitting means as a gear 37 mounted on the main shaft and meshing with the gear 38 mounted on the axle of one of the sheaves 6, and with an intermediary gear 39 which in turn meshes with a gear 40 mounted on the axle of one of the upper sheaves 5. The motion is transmitted to the sheaves 29 and 30 in order to rotate said sheaves in opposite directions by means of belts 41, 42.

In operation, the branches, the bark of which is to be rossed are placed on the projection portion of the lower belt member 4 and carried by said member over the abrading member 34 and under the deflector 32 and are then carried between the belt members 3, 4; and owing to the arrangement of the sections or ropes of such belt members, such ropes engage each branch'at three sides, and in passing through between the pressure rollers the bark is loosened on the branches. From between the belt members 3, 4 the branches are passed through thestrippers 26 and thence to the belt members 27 and 28, which are rotated at a greater speed than the belt members 3, 4 and therefore draw the branches at accelerated speed through the strippers 26. Owing to the fact that the upper and lower pressure rolls are out of a vertical line the pressure of such rollers is not applied at diametrically opposite points of the branch and thus breaking or crushing of the branch is avoided.
